Chemotactic speed of wild type and regA- amoebae. The effect of preincubation with EGTA for 30 min was assayed. Chemotactic velocity of amoebae was affected dose dependently by EGTA treatment; when compared to the wild type the speed of the regA- strain was significantly reduced at lower concentrations of EGTA. Velocity of wild type and regA- cells is shown (median of at least 2 independent experiments).
